Bought a Ryobi 12" bench drill press this weekend. The runout, as measured
with a blank reamer shaft is 0.012". Seems a little excessive to me. I think
I'll return it to the store (HD). I do not think I am being unreasonable. Or
Don't know what you paid, but a review I recently read of 4 benchtop presses
provided these measurements:
Bridgewood: 0.008" ($219)
Powermatic: 0.004" ($350)
Grizzly: 0.009" ($280)
Jet: 0.008" ($319)
I"ve got a delta with no measureable runout on the 16 1/2" model. I
forget the model number but it's the popular floor standing model they
had out earlier this year, and prior.

Seems to me Dave, that the last time this was discussed, it turned out your
measurement tool was you eyeball. If you can't measure it, maybe me and my
indicator should take a trip south. Only got to cover a state and a half. :)
when there is no visible runout, that's good enough for me, my
cantankerous, ornery, argumentative friend. If something with a chuck
spins dead accurately, I don't need to grab my dial indicator. I bought
a Dewalt cordless drill with so much run out even you wouldn't have
bothered with using a indicator on it; I merely returned it for a refund
and got a Makita. I repeat, my DP has no "discernible" run out. is
that more to your liking, rather than "measurable"? picky, picky, picky.
Yep. Meaningful run out can be easily seen.

As you should have.
No, you said that it didn't have any measurable run out. Obviously, I knew
what you meant but the original poster, after seeing comments like that,
could very well come to the conclusion that that is the way his should be.
It is a rare chuck that shows no run out at all. In any case, for this type
of measurement, I think your method is to be preferred. In many cases, a
sensitive measuring instrument will give one something to worry about when
it actually is of no consequence. The .012 measurement the OP got is rather
excessive but usable. He will likely want to do better. It would also be
clearly discernable by eye. I do have a collection of indicators due to
professional need though I really use one in the woodshop. Seldom is it
Damn, reading this news group is a pain. Read something,
run out to the shop and check, read something else, run out
to the shop and check, repeat, repeat.
Well, I ran out to the shop to check my little HF $40 drill
press. I thought it was excellent, little noise, no
vibration, but obviously lacking power for big jobs. I hope
I did this right, I put a 7/16 drill in the chuck, set the
arm of the dial gage against the drill near the chuck, and
rotated the motor to turn the drill. The range was 0.002
There was a long thread about chucks falling out of drill
presses and how to clean and put the chuck in. When I got
my DP, I cleaned everything really well, stuck the chuck on
the spindle, opened the chuck wide, put a board on the
chuck, and gave the board a whack with a ball peen hammer.
Like Greg O said, maybe a lot of runout is related to how
well everything is cleaned before setting the chuck.
Well, that just goes to prove that you get what you pay
for. Plumb Bob got 0.012 inch runout for $169, and I got
0.002 inch runout for $40. Hell, I paid $20 per thousandth
runout and Plumb Bob only paid $14 per thousandth runout.
Hell of a deal. How come I always get screwed.
